Abstract
A condensing zone is arranged downstream of the main drafting area of a drafting assembly of a ring spinning machine, which condensing zone is defined on one side by a front roller pair of the drafting assembly and on the other side by a nipping roller which presses a drafted fiber strand against a supporting surface. The peripheral speed of the nipping roller is from 3% to 8% greater than the peripheral speed of the front roller pair. The fiber strand to be condensed obtains thus a lasting draft in the condensing zone.
